In situ X-ray absorption near edge structure (XANES) investigations were carried out at chlorine K edge and palladium L3 edge to study the mechanism of the thermal decomposition of ammonium hexachloropalladate. The spectra show a characteristic feature for the initial step that might be explained as the formation of the precursor via ligand exchange (Cl --> NH3). Multiple scattering calculations (Feff 8) for the Cl K, Pd and Rh L3 edges were successful in simulating the XANES spectra of the precursor as well as the reference compounds (NH4)2 [PdCl4] and (NH4)3[RhCl6].
采用原位X射线吸收近边结构（XANES）技术，在氯K边和钯L3边进行了研究，以探究六氯钯酸铵热分解的机理。光谱显示了初始步骤的一个特征，这可能解释为通过配体交换（Cl→NH3）形成前驱体。对Cl K、Pd和Rh L3边的多重散射计算（Feff 8）成功模拟了前驱体以及参考化合物（NH4）2[PdCl4]和（NH4）3[RhCl6]的XANES光谱。
